Why is my fairy flax growing tall and leggy?

Fairy flax naturally wants to grow in bright, direct sun. When it gets leggy, it is almost always stretching out to find more light.

Check these first

  1. Observe the light levels in your plant's current spot.
  2. Rotate the pot to see if it stops leaning.
  3. Measure the distance between the leaves.

Likely causes

  1. Insufficient Light

    Most likely

    How to tell: The stems are long and thin with large gaps between the leaves. The plant leans heavily toward the nearest window.

    What to do: Move your plant to a spot that receives full, direct sun for most of the day. If you are growing indoors, place it in a south facing window.

  2. Crowding

    Possible

    How to tell: The stems are thin and weak because they are competing for light with other plants. The plant looks thin rather than bushy.

    What to do: Space your plants out to ensure each one gets full exposure to the sun. You can also prune back the longest stems to encourage fuller growth.

When to worry

Legginess is not a disease, but it makes the plant weak and prone to falling over. It is normal for the plant to grow taller as it matures, but it should remain sturdy.

Stopping it coming back

Provide as much direct sunlight as possible throughout the day. Rotate the pot weekly so all sides get equal light exposure.

Questions people ask

Should I prune the leggy stems?
Yes, pruning the long, thin stems will encourage the plant to branch out and grow more compactly. Use clean scissors to trim the stems back by about one third.
Does fairy flax flower if it is leggy?
Fairy flax produces small white flowers when it has enough energy from full sun. If it is leggy, it likely lacks the energy to bloom.
